2 How do macroeconomic or industry factors influence R&D project s 1 value (NPV) 2 success 3 failure... over time?
3 We present a novel valuation model based on real options 1 that incorporates the impact of external forces, such as market conditions, economic uncertainty, innovation, firm competition on the cash flow generation 2 that features an option to abandon 3 that enables to estimate the impact of these external conditions on the optimal launching time for the project as well as on success or failure rates of the project Our practical case covers a pharmaceutical R&D project, but the model and methodology can be easily extrapolated to any industry
4 The literature has shown the economic and social impact of R&D projects as well as the impact of the economic and social context on R&D spending International context, GDP as determinants of public spending in research and developments (Hammadou et al., 214, RP) Effect of public funding on innovative projects (Lanahan and Feldman, 217, RES) Productivity growth and R&D expenses (e.g. Kancs an Siliverstovs, 216, RP) Social and economic impact of R&D (e.g. Brautzsch et al., 215, RP; Ugur et al., 216, RP)

6 Literature Review Our contribution: modeling external forces Project s value
7 Theoretical framework Literature Review Our contribution: modeling external forces Project s value In the extant literature, real options have been used to model staged investments (e.g. Madj and Pindyck, 1987, JFE; Berk et al., 24, RFS) the optimal timing of investments (e.g. McDonald and Siegel, 1986, QJE; Posner and Zuckerman, 199, JAP) the impact of uncertainty in cash flows and cost on the project s value and risk (e.g. Schwartz, 24, EN; Berk et al., 24, RFS)
8 Theoretical framework Literature Review Our contribution: modeling external forces Project s value Modeling choices Modeling project s market value (e.g. Madj and Pindyck, 1987, JFE; Pennings and Sereno, 211, EJOR; Alexander et al., 212, EJOR) Modeling project s cash flows (e.g. Berk et al., 24, RFS; Schwartz, 24, EN) Modeling cost of completion and expenditures (e.g. DiMasi et al., 23, JHE; Pindyck, 1993, JFE; McDonald and Siegel,1986, QJE) Modeling technical risk (e.g. Schwartz, 24, EN ; Pindyck, 1993, JFE ; Pennings and Sereno, 211, EJOR)
9 Theoretical framework Literature Review Our contribution: modeling external forces Project s value In the literature, it is common to model the evolution of the project or the evolution of the cash flow as a stochastic differential equation... Geometric Brownian motion Arithmetic Brownian motion Ornstein-Uhlenbeck process dc t = µ(c, t)dt + σ(c, t)dw These models account for market uncertainty and idiosyncratic risk of the project but not for external cyclical forces
10 Theoretical framework Literature Review Our contribution: modeling external forces Project s value To account for technical risk, we generalize the Poisson distribution... Probability of success = e λ Probability of technical failure = λ k e λ =1 e λ k! k=1
11 Theoretical framework Literature Review Our contribution: modeling external forces Project s value The expected project value conditional to technical risk is given as E [V Technical Risk] = V (k =) e λ + V (k =1, 2,..., ) (1 e λ) Assuming V (k =1, 2,..., ) = During the development process the discount factor is given by e r d t = e (r+ˆλ)t
12 Theoretical framework Literature Review Our contribution: modeling external forces Project s value All these models share the same source of uncertainty... Arandomwalkweightedbyσ(C, t) forcapturingmarketand idiosyncratic risk APoissondistributiontoaccountfortechnicalrisk No model accounts for... Seasonal effects Business cycle Other relevant external forces
13 Economic and market external forces Literature Review Our contribution: modeling external forces Project s value Consider the net cash flow stream of a successful project C t = f (t)+y t Where dy t = µdt + σdw t Arithmetic Brownian motion f (t) = Fourier series The net cash flow of a successful project is given by an arithmetic Brownian motion process plus a time-dependent component depicted by a Fourier series. The Fourier series is a function defined as the sum of a set of simple sines and cosines, representing all the forces that impact the generation of cash flows.
14 Cash flow generation Literature Review Our contribution: modeling external forces Project s value Under the risk neutral probability P Q,thesolutionatanygiventimet is t Y t = Y e rt + σ C t = Y e rt + f (t)+σ e r(t s) dw Q s t e r(t s) dw Q s where Wt Q P Q. is a standard Wiener process under the risk-neutral measure
15 State vector Literature Review Our contribution: modeling external forces Project s value Let s define the economic state vector... Φ (j) with j N Each state...
16 State vector Literature Review Our contribution: modeling external forces Project s value Let s define the economic state vector... Φ (j) with j N Each state... corresponds to a specific scenario described by the cyclicality and the phase of the economic forces
17 Patent value Literature Review Our contribution: modeling external forces Project s value The expected patent value conditional to certain economic state is given as... E [ V Φ (j)] ( = V t, C t, I t ;Φ (j)) Pr (Φ =Φ (j))
18 Simulation exercise
19 Pharmaceutical project s stages Two major phases... 1 Research and development phase 2 Market phase The failure of one stage leads to overall project termination. We assume that once the project successfully passes every test and stage of the R&D process and finally achieves regulatory approval, technical risk virtually vanishes.
20 Economic forces For the sake of simplicity let s assume two economic forces... 1 US Gross domestic product (GDP) The business cycle is defined as the cyclical movement of the GDP around its long-term trend Hodrick-Prescott (1997) filter to disentangle the cyclical behaviour from the long-term trend 278 quarterly GDP observations ranging from January 1947 to April 216, obtained from the Federal Reserve Bank of St. Louis web page 2 VIX index Barometer of investor sentiment and market volatility Hodrick-Prescott (1997) filter , monthly observations provided by the Chicago Board Options Exchange (CBOE)

29 We perform a new exercise fitting the parameters of the fourier series to cash flow data of pharmaceutical firms active in anti-infective drug New external forces are assumed to better impact a specific pharmaceutical project Economic and political (business cycle and economic policy uncertainty index) Innovation (R&D expenditure as % of GDP, patent applications) Health expenditures (per capita, out of pocket) Competition (H concentration index based on sales)
30 New simulation exercise We consider the impact of these forces on a hypothetical project s success, abandon rate and value The project has an initial cash-flow of 1 M$ (5 M$ standard deviation) per quarter with an initial cost to completion equal to 1 M$ (sigma=.5) US versus Europe (EU) Big versus small caps

46 We have... developed a novel valuation model and methodology to value a (pharmaceutical) R&D project based on real options approach performed simulation analyses considering the interaction ofdifferent external economic and market forces shown that the same project launched in different countries or bydifferent firms (small or large) might have different success and abandon ratesdueto the impact of the economic and industry contexts Our research provides managers with an important tool for timing the introduction of an R&D product to the market.
